Martin Jansa caaa5709b4 update-modules: update script to read /etc/modules-load.d/ directory
* show warning for old /etc/modutils/* files without .conf extension
* v2: keep adding modules also from old /etc/modutils/* after showing
  warning, this way update-modules will be backward compatible also on
  images without kernel upgrade

well we're using /etc/modprobe.d/.conf instead of /etc/modutils/.conf anyway..

Don't run modutils.sh if systemd is installed

if [ $first_time -eq 1 ] && [ ! -e /bin/systemctl ]; then /etc/init.d/modutils.sh || true fi

We also call depmod here to stop insmod from complaining that modules.conf

is more recent then modules.dep

if [ -d "depdir" -a -f /proc/modules ] then depmod -A || true fi
